Melatonin-Mediated Molecular Responses in Plants: Enhancing Stress Tolerance and Mitigating Environmental Challenges in Cereal Crop Production

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(8), P. 4551 - 4551

Published: April 21, 2024

Cereal crops are crucial for global food security; however, they susceptible to various environmental stresses that significantly hamper their productivity. In response, melatonin has emerged as a promising regulator, offering potential benefits stress tolerance and crop growth. This review explores the effects of on maize, sorghum, millet, rice, barley, wheat, aiming enhance resilience stress. The application shown outcomes, improving water use efficiency reducing transpiration rates in millet under drought conditions. Furthermore, it enhances salinity heavy metal by regulating activity stress-responsive genes. Similarly, sorghum its resistance high temperatures, low humidity, nutrient deficiency, potentially involving modulation antioxidant defense aspects related photosynthetic Melatonin also exerts protective against drought, salinity, metal, extreme waterlogging barley decreasing reactive oxygen species (ROS) production through system. molecular reactions upregulated photosynthesis, mechanisms, metabolic pathway, genes downregulated susceptibility conclusion, serves versatile tool cereal crops, bolstering promoting sustainable development. Further investigations warranted elucidate underlying mechanisms refine techniques fully harness role systems.

Fighting to thrive via plant growth regulators: Green chemical strategies for drought stress tolerance

Physiologia Plantarum, Journal Year: 2024, Volume and Issue: 176(6)

Published: Nov. 1, 2024

As global climate change intensifies, the occurrence and severity of various abiotic stresses will significantly threaten plant health productivity. Drought stress (DS) is a formidable obstacle, disrupting normal functions through specific morphological, physiological, biochemical, molecular mechanisms. Understanding how plants navigate DS paramount to mitigating its adverse effects. In response DS, synthesize or accumulate growth regulators (PGRs), including phytohormones, neurotransmitters, gasotransmitters, polyamines, which present promising sustainable green chemical strategies adapt tolerate conditions. These PGRs orchestrate crucial structure function adjustments, activating defense systems modulating cellular-level responses, transcript levels, transcription factors, metabolic genes, stress-responsive candidate proteins. However, efficacy these molecules in depends on species, applied PGR dose, treatment type, duration exposure, stages. Thus, exploring integrated impact enhancing fitness tolerance for food security agriculture. This review investigates responses explains potential exogenously diverse PGRs, dissects complex chemistry among sheds light omics approaches harnessing basis tolerance. updated delivers comprehensive mechanistic insights leveraging enhance overall under

Association Mapping for Components of Reaction Norms to Environmental Covariates in Public Tropical Maize (Zea mays) Panel Under Water Stress

Plant Breeding, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 13, 2025

ABSTRACT Using reaction norm components instead of traditional phenotypic data in genetic association studies (GWAS) may allow the identification genomic regions that are more influenced by environmental variables terms tolerance and responsiveness to water stress. To test this hypothesis, we used a public diversity panel tropical maize inbred lines, evaluated eight environments, four well‐watered (WW) stress (WS) conditions. Most SNPs explained at least 40% variability, some reached 67%. The identified genes revealed physiological responses direct or indirect molecular mechanisms related deficit responsiveness. This information will enable assertive selections subsidize breeding programs aimed obtaining cultivars for conditions while reducing costs evaluation processes standards.

Comprehensive transcriptomic and metabolomic analysis revealed drought tolerance regulatory pathways in upland cotton

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: April 17, 2025

Cotton is a kind of cash crop widely planted in arid and semi-arid areas. In this study, we performed multi-omics analysis two drought resistant extreme materials, Yumian 4 C460, under stress. Transcriptome showed that DY (post-drought stress 4) had more differentially expressed genes than DC C460), there were 10247 DEGs the comparison groups. Metabolomics identified 1766 metabolites, which divided into 12 classes. The up-regulated metabolites mainly included lipid accumulation, phenylpropanoid biosynthesis, flavonoids. combined transcriptome metabolome highlighted importance biosynthesis enhancing tolerance. Combining omics analysis, it was found enrichment pathway differential phenylpropane pathway, contains 23 related candidate genes. summary, results resistance cotton materials they enhanced by affecting pathways. Promote accumulation osmotic substances. further deepen our understanding molecular mechanism tolerance provide new insights for breeding cotton.
